Why do receptacles crack?
Another very common problem with receptacles that receive a lot of use is that the circuit wire connections begin to loosen. Each time current is drawn through a wire connection, a small amount of heat is generated, and this repeated expansion and contraction of the wires can eventually cause the screws to loosen. You may hear the receptacle begin to crackle when this happens, and if the wire connections come loose entirely, a short circuit may cause the circuit breaker to trip.
